This is my story;
Son of House Leveilleur, Born to Fourchenault Leveilleur, a Sharlayan dignitary and son of Louisoix Leveilleur, in the Dravanian Hinterlands within Ishgard, Alphinaud and his sister attended the Studium at a young age and were given grimoires by Louisoix before he left for Eorzea. The twins were unaware that their tomes were halves of a larger grimoire, signifying Louisoux's wish for the twins to understand each other and share a common goal.
It was at the tender age of eleven that Alphinaud and his twin sister, Alisaie, were accepted into the prestigious Studium. There, he specialized in the study of arcane entities, history, and natural history, and pursued advanced studies in the magical arts and aetherology. Upon graduating at sixteen, the Sharlayan age of adulthood, he resolved to sail for Eorzea in spite of his father's objections. Alphinaud has since worked to see his grandfather's wishes made a reality. It is why he joined the Scions, and later why he founded the Crystal Braves. His path would set him upon a journey deep into the heart of the Dragonsong War, where his experiences and encounters would see him grow and mature as a person.
To say Alphinaud is a man of many talents is an understatement. In addition to his scholastic feats, he is also a talented artist, his specialty being portraits. One will not, however, see him taking up his brush and pallet for Krile Baldesion—a young woman for which he bears some annoyance due to her peculiar tendency to know too much.
so read carefully,
Alphinaud is a sixteen-year-old Elezen with white hair. He wears a large delta-shaped earring on his left ear and dark blue clothing that matches his sister's. He has a blue knot on his ponytail and green markings on his collar. He seems to be an Arcanist, as he wields a black grimoire. During Final Fantasy XIV: Heavensward, at Tataru Taru's behest, Alphinaud wears a white tunic with matching pants and boots, a blue coat with a black hood, and black gloves. He also has a Ruby Carbuncle companion.
The most distinct feature Alphinaud has from his sister, aside from the color of their ponytail and collar markings, is the color of their lips. Alisaie's are redder, being female and possibly wearing lipstick. The duo becomes more distinctive in Heavensward once Tataru provides them with new outfits.
In Final Fantasy XIV: Shadowbringers, Alphinaud is seventeen years old and is given a new outfit that resembles the one he was given in Heavensward, only simplified and more armored, and his iconic Arcanist tome changes to a wooden tome. After his journey in the First and returning to the Source, Alphinaud returns to his Heavensward outfit.
or you might just miss something.
Alphinaud is a self-assured young man, calm and mature for his age. He shows more interest in intervening in the events of Eorzea than his sister, who prefers to watch history unfold from the shadow. Charismatic and diplomatic, he finds it easy to gain the Eorzean Alliance leaders' trust, partly thanks to his grandfather's credit. Alphinaud has a big ego and often clashes with other nations' leaders about their ideals. Alphinaud has a tendency to listen and partake in gossip.
Initially, Alphinaud participates in Eorzea's affairs with his own agenda: to find out what happened to his grandfather and finish what he started to test his potential and prove himself. As he spends more time with the Scions he comes to understand why his grandfather sacrificed so much for the realm and resolves to follow in his footsteps.
Alphinaud is not invulnerable to negative feelings, as he regrets his mistakes and overconfidence. He gets flustered whenever Krile or Alisaie threaten to regale embarrassing details from his earlier days in the Studium in front of the Warrior of Light. Alphinaud is annoyed and embarrassed for being mistaken for his sister, or a girl in general. Despite his differences with his sister, Alphinaud deeply cares about his twin and dreads losing her.
In Heavensward, Alphinaud comes to terms with the Crystal Braves' betrayal and of his own naivete, maturing during his time in Ishgard. Upon reestablishing the Scions of the Seventh Dawn, his leadership qualities come to light as its remaining members name him the guild's de facto leader, which he humbly accepts.
Though good-natured and welcoming, Alphinaud can hold a grudge if someone betrays his trust for selfish desires or harms his friends. He matures into a capable leader and crafts the plan to liberate Doma from Garlean rule and offers to go to Garlemald as a diplomat following the successful prisoner exchange. Alisaie remarks that her brother always had a flair for politics while Hien Rijin notes he has a talent for formulating plans. Despite his maturity, Alphinaud has moments of being impudent as he couldn't control his laughter at Gosetsu being tended to by an amnesiac Yotsuyu or with Alisaie's lackluster clay art piece.
"ᏕᏗᎶᏋ ᎧᎦ ᏝᎥᎶᏂᏖ"
"Whenever the realm is threatened, be it by primal, Ascian, Garlean, or any other, we take up arms in her defense, that all in Eorzea may live to see a brighter tomorrow."
"If it's healing, please leave it to me!"
Alisaie: And now I don’t know what to do.
Alphinaud: I think you do know what to do.
Alisaie: Thanks, Alphinaud.
WoL: What’s she gonna do?
Alphinaud: I actually have no idea, but that’s the safest way to give Alisaie advice.
